ALFRED H. NEWPHER, F CHICAGO, ILLINOIS, .ASSIG'NOR TO THE ADAMS & WESTLAKE 'y COMPANY, `Av CORPORATION OF ILLINOIS.

WINDOW-SCREEN.

To all whom 'it may concern:

Be it known that I, ALFRED I-I. NEWPHER,

` a citizen of the United States, and resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Window- Screens, of which the following is a specilication, and which are illust-rated in the accompanying drawin s, forming a part thereof.

The lnvention relates to screens for windows.

The object of the invention is to provide for an adjustable lit of the screen sash against the frame within which it is mounted; more particularly, to provide a close joint between the bottom bar of the framey and the window sill, though applicable to other'bars of the screen frame which abut against members of the -window frame.

'Ihe invention consists of a structure such as is hereinafter described and illustrated in the aocompanyin drawings, in which- Figure 1 is a etail perspective, partly in section,.of a window screen and the window frame to which it isl fitted; Fig. 2 is a detail longitudinal vertical central section of one of the bars of the screen; Fig. 3 is a detail sectional view on the line 3 3 of Fig. 2; Fig. 4 is a detail sectional View on the line 4-4 of Fig. 2; Fig. 5 is a detail perspective of an adjustable strip carried by one of the bars of the screen; Fig. 6 is a detail longitudinal section in perspective of a screen bar with a modified form of adjustable bar and spring; Fig.-7 is a detail section on the line 7 -7 of Fig. 6; Fig. 8 is a similar view showing a further modification; Fig. 9 is a perspective, in detail, of the adjustable bar shown in Fig. 8; and Fig. 10 is a perspective of the spring shown in Fig. 8.

The sill of a window is shown at l0, andone of the frame Stiles thereof at 11. The window screen comprises a frame either of wood or metal, two sides only of which, designated by the numerals 12 and 13, are

-Shown in the drawings; and a reticulated screen 14 secured to the frame in any suitable manner.

The bars of the frame of the screen which make contact with the Window casing, some or all of them, are longitudinally channeled in their outer faces, as shown, with reference to the lower bar, at 15. Within this channel 15 there isloosely fitted a metal Letters Patentlllatented Sept. 27, 1910. 1910. serial No. 571,529.

tubular bar 16, preferably rectan ular in cross-section and having its inner ace longitudinally slotted, as shown at 17.

A leaf spring 18 (or preferably a plurality of such springs) is secured midway of its ends to the bottom wall of the channel 15 by any suitable means, such as the screw 19. The outer ends of the spring 18 are inclined outwardly and provided with laterally projecting lugs, shown as taking the form of studs 2O 20, the heads of which are directed outwardly and spaced apart from the outer face of the spring. The bar 16 is secured within the channel 15 by sliding it in longitudinally, .its flanges 21, 22, which form its inner wall, entering between the heads of the studs 20, 20, and the spring 18. When the bar 16 is applied to the lower bar 12 of the screen, it tits snugly against which are spaced apart from the body of the j bar.

rFlie spring 2G is of leaf form and at its end is provided with down-turned lateral lugs 27, 28, between which the shoulders 2-1, 25 are slidingly received.

It is not essential that the shoulders of the bar for engaging the lugs of the spring shall extend the entire length of the bar.

In Figs. 8, 9 and 10 a modification is shown in which the bar 29 is tubular in form and is provided with a pair of key-hole shaped apertures 30, 31. The spring 32 has at each end a pair of laterally projecting downwardly inclined lugs 33,` 34, which may enter the enlarged portion of the apertures 30, 31, and slidingly engage the contracted portions thereof. For convenience lin assembling the bar 29 is apertured as lshown at 35 to accommodate a screw driver. The

spring is preferably iitted to the bar before a screen it is obvious that the invention is adapted as Well to glazed sash.

l claun as my inventionls. A sash frame having a longitudinal channel in the outer ed e of one of its bars, a bar fitting loosely Wit in the channel and having longitudinal shoulders, and a spring secured to the. sash bar Within its channel and having shoulders slidingl engaging the shoulders of the second name bar.

2. A window screen having the outer face of one of its bars longitudinally channeled, a leaf spring secured Within the channel and having its ends projecting outwardly and being provided With lugs having lateral shoulders, and a tubular bar fitting loosely Within the channel andhaving its inner face longitudinally slotted, the lugs on the spring entering such slot.

3. A Window screen having the outer face W of one of its bars longitudinally channeled,

a leaf spring secured to the bottom of the channel and having its ends projecting outwardly and being provided With lugs having lateral shoulders, and a tubular bar fitting loosely Within the channel and having its inner face longitudinally slotted, the lugs on the spring entering such slot.
